Expression Editor

• May 27, 2025

The Expression Editor provides the capability to create and edit expressions in DevExpress WPF controls (for example, Data Grid). The expression editor supports numerous standard functions and operators that allow you to perform different string, date-time, logical and math operations over data.

Note

The Expression Editor is not available in the new WPF XAML Designer. For information on the difference between the old and new WPF XAML designers, refer to the Quick Actions and Smart Tags section.

The Expression Editor is not intended to be used in Windows Forms hosted applications.
